Denial of Service (Dos)

Cyber Attack

What is a Dos?

What is a Denial of Service attack? 

A DoS attack focuses on disrupting the service to a network. Attackers send high volumes of data or traffic through the network (i.e. making lots of connection requests), until the network becomes overloaded and can no longer function.

How does it work? 

There are a few different ways attackers can achieve DoS attacks, but the most common is the distributed-denial-of-service (DDoS) attack. This involves the attacker using multiple computers to send the traffic or data that will overload the system. In many instances, a person may not even realise that his or her computer has been hijacked and is contributing to the DDoS attack.

Disrupting service can have serious consequences relating to security and online access. Many instances of large scale DoS attacks have been implemented as a sign of protest toward governments or individuals and have led to severe punishment, including jail time.

How can I prevent it? 

Unless your company is huge, it’s rare that you would be targeted by an outside group or attacker for a DoS attack. Your site or network could still fall victim to one, however, if another organisation on your network is targeted.

The best way to prevent an additional breach is to keep your system as secure as possible with regular software updates, online security monitoring and monitoring your data flow to identify any unusual or threatening spikes in traffic before they become a problem. DoS attacks can also be perpetrated by simply cutting a cable or dislodging a plug that connects your website’s server to the internet, so due diligence in physically monitoring your connections is recommended as well.
